DETAIL DESCRIPTION OF THE INVENTION

Now make further detailed description for the utility model, combiningthe execution example of the attached drawing.

As it is shown in drawing 3, the outdoor wind proof umbrella includesumbrella cover, umbrella framework, which, as the center of the umbrellacloth of the umbrella cover, is fixed between the umbrella cap of theumbrella framework and umbrella disk of long rib. The long rib umbrelladisk 10 is fixed to the top of upright post of umbrella, and the slidingshort rib umbrella disk 11 is set on the middle part of upright pole 12of the umbrella. There is one umbrella cap 9 on long rib umbrella disk10. One side of main long rib 1 supporting the umbrella cover isactively connected to fixed long rib umbrella disk 10. One side of theshort rib 6 supporting the main long rib 1 is actively connected tosliding short rib umbrella disk 11 with the help of retainer 7 ofumbrella rib, and screw or rivet 8 is used to hinge the other side ofthe short rib 6 to the retainer 3 of main long rib fixed at the middleof the main long rib 1. As it is shown in drawing 1, it can be hinged bysupporting the convex lug 19 of main long rib 1, see drawing 6, 7. Inwhich, one side of flexible rib 5 is fixed by rivet or screw 15 on theupper part of main long rib 1 and is extended to external side along thetop of main long rib to form the long rib and at the same time, piecefor blocking the cloth 2 is set on the external side of the main longrib 1. In order to increase the general intensity of umbrella cover andflexible rib, more than one auxiliary flexible rib will be set on themouth part of the main long rib 1; the flexible rib and auxiliaryflexible rib will form the overlapped stairs to be staggered. As it isshown in drawing 7, main long rib 1 can combine with the auxiliaryflexible rib 3′, 3, 18 to form the shape of overlapped stairs. Theflexible rib 5 is fixed under U shape fastener 4, which can be set asthe fixed or sliding part. U shape fastener 4 can be stuck at two sidesof flexible rib 5, which can prevent the flexible rib from swinging andcan increase the stability of umbrella and will make the flexible rib ofthe main long rib 1 straight and the umbrella cover more beautiful. Thepiece for blocking the cloth 2 is fixed on the other side of main longrib 1 and fixed long rib umbrella disk 10, which can prevent theflexible rib 5 from dislocated falling after the umbrella cover 17 andflexible rib 5 is connected, and can make main long rib 1 and flexiblerib 5 straight and the umbrella cover more beautiful. The material ofthe flexible rib 5 and auxiliary flexible rib is the glass fiber rib orsteel wire. The shape of rectangle, square, trapezoid, triangle or theround is adopted on the rib's cut section. Outdoor upright umbrellastand or outdoor sunshade umbrella stand is adopted for the umbrellaframework.

When the umbrella framework is in status of closing, main long rib 1 andflexible rib 5 and short rib 6 and upright post of umbrella 12 are closeto vertical line so that the packing size of the umbrella will notincrease. When the umbrella framework is pushed open, shown as indrawing 1 and drawing 6, the flexible rib 5 will be pushed open withmain long rib 1 and umbrella cover 17 will be in muff coupling withflexible rib 5 overlapped on the main long rib 1. This structure canreduce the possibility that the main long rib 1 will be bended fortransformation or broken due to the external force. Especially when thewind is exerted on umbrella cover 17 from inside to outside to make theframework turn outward, the umbrella cover 17 can bring the overlappedflexible rib 5 of main long rib 1 to extend to certain degree, (as shownin drawing 4). So when the wind blows in front of the top of umbrella orblows at the bottom side, the umbrella rib is flexibly bended and willnot be broken, which can reach the effect of wind proof.
